Steve cut a circular piece of mirrored glass with a diameter of 20 centimeters. In order to make a frame for it, he needs to calculate the circumference. What is the circumference, in centimeters, of the piece of mirrored glass? A. 10
B. 207
C. 407
D. 1007​

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.
